Web Accessibility Initiative - Accessible Rich Internet Applications (WAI-ARIA) is a set of guidelines designed to make web content more accessible for people with disabilities. One important attribute introduced by WAI-ARIA is the aria-grabbed attribute. In this blog post, we will explore the purpose and usage of the aria-grabbed attribute.

Introduction to aria-grabbed

The aria-grabbed attribute is used to indicate whether an element is currently selected or grabbed. It is primarily used in drag-and-drop interactions or elements that can be selected or manipulated through user interaction.

By setting the value of aria-grabbed to “true”, the assistive technologies will interpret the element as currently selected or grabbed. Conversely, setting the value to “false” will indicate that the element is not selected or grabbed.

Usage of aria-grabbed

To use the aria-grabbed attribute, you need to add it to an element that is selectable or draggable by the user. The value of the attribute should be set dynamically based on the user’s interaction with the element.

Here’s an example usage of aria-grabbed in HTML:

<div id="draggable-element" role="button" tabindex="0" aria-grabbed="false">
  Drag me
</div>

In the above example, the div element with the id “draggable-element” is made draggable by using the role attribute with the value “button”. The aria-grabbed attribute is initially set to “false” indicating that the element is not yet grabbed by the user.

When the user starts dragging the element, you can dynamically update the aria-grabbed attribute to “true” using JavaScript to indicate that the element is grabbed.

const draggableElement = document.getElementById("draggable-element");

draggableElement.addEventListener("dragstart", () => {
  draggableElement.setAttribute("aria-grabbed", "true");
});

draggableElement.addEventListener("dragend", () => {
  draggableElement.setAttribute("aria-grabbed", "false");
});

By updating the aria-grabbed attribute, screen reader users will receive live updates about the status of the element, ensuring a more inclusive experience.

Conclusion

The aria-grabbed attribute is a valuable addition to WAI-ARIA as it improves the accessibility of web applications that involve draggable or selectable elements. By using this attribute appropriately, developers can provide more information to assistive technologies and ensure users with disabilities can fully engage with the web content.
